#### Filters Tab - Adaptive Cylinder Spiral Scan Strategy

Use the Filters tab for the Adaptive Cylinder Spiral Scan strategy to set up filters.

Outlier

PC-DMIS first fits a circle to the data and then determines which points are outliers based on the standard deviation multiple. It then does the following:

- Recalculates the best fit circle with those outliers removed.

- Checks for outliers again.

- Recalculates the best fit circle.

- Continues repeating this process until no more outliers exist or until PC-DMIS cannot compute the circle. (PC-DMIS cannot compute the circle if there are fewer than three data points.)

Filter

This value indicates the filter type for the scan. Some filtering options are specific to certain strategies. Select the filter type:

- None - Does not apply any filter type to the scan data set.

- Gaussian - Applies a Gaussian filter to the scan data set, which smooths the data.

UPR

Type or select the undulations per revolution. The default is 50. The UPR applies only to cylinders and circles. This item is hidden if you select None in the Filter list.
